1.3 Logical Partitions for AlphaServer GS140 System
The logical partitioning feature allows a single AlphaServer GS140 system to
be partitioned into as many as three logical partitions. Each partition runs a
separate instance of the operating system. For a complete description of
logical partitions, refer to the System Adminstration guide.
The minimum AlphaServer GS140 firmware revision for logical partitions
support is Version 5.4.
At the time of Version 4.0F release, the AlphaServer GS140 Model 6-525 is
the only system supported for logical partitioning. Refer to the Systems and
Options Catalog for information on newly-supported systems.
1.4 Dynamic Host Configuration Protocol
This version of Tru64 UNIX includes an upgraded and improved Dynamic
Host Configuration Protocol (DHCP) database. The new database supports a
new database format. Therefore, if you are currently using DHCP from a
prior version of Tru64 UNIX, you must convert the database to the new
format.
The improvements to DHCP include:
• Force broadcast reply
• Ignore hardware type
• Return bootfile in header
• Server policy consistency check
• Allow the server canonical name
For more information on DHCP, see the Network Administration guide, the
Technical Overview, and the joind(8) reference page.
1.5 ATM PACING VC Bandwidth Accounting Change
In this release, the bandwidth used by pacing virtual circuits (VCs) is not
deducted from the total bandwidth in the constant bit rate (CBR) reserved
resource pool. Therefore, ATM drivers can now overbook the driver’s
bandwidth. In addition, reserved resources can be applied to CBR VCs only.
In previous releases of the operating system, the bandwidth used by pacing
VCs was deducted from the total bandwidth in the constant bit rate (CBR)
reserved resource pool. This prevented ATM drivers that supported paced
unspecified bit rate (UBR) traffic from allowing paced VCs to overbook the
driver’s bandwidth.
